Reading custom fields using alarm properties does not work.

KANG

Hello. I'm KANG.

I'm using the alarm property to show the ability to read or write a value. Most are using analog alarms.

For example, if the name of analog alarm tag is 'AT0001', the setting value of High High can be read or written as 'AT0001.HighHigh'.

I registered a custom field among them.
However, if I try to read the value as 'AT0001.custom1', an empty string is returned.

What if I want to return the value entered in the custom field?

  • Hi KANG / Olivier,

    This is a "feature" [I agree, it's a bug ]

    A possible workaround is to use [Alarm]UseConfigLimits=1 to force using the RDB rather than the database.  You should then be able to read and write to the custom fields with no problems ?

    Edit: I should add that I've only used this in 2018 but suspect it's the same in 2016 !?!

    Cheers,

    Roger.
